Physical properties
Hardness: 7, Color: variable (clear to smoky with metallic or dark inclusions), Luster: vitreous, Crystal structure: trigonal, Cleavage: poor/indistinct, Fracture: conchoidal
Formation & geological history
Formed in igneous, metamorphic, or sedimentary environments. This specimen appears to have grown in a hydrothermal vein or pegmatite, incorporating other minerals during its formation.
Uses & applications
Quartz is used in glassmaking, electronics, and construction. Aesthetically pleasing specimens are collected or used in jewelry.
Geological facts
Quartz is one of the most abundant minerals on Earth's surface. Inclusions can often help determine the geological environment in which the quartz formed.
Field identification & locations
Identify by its hardness (scratches glass), conchoidal fracture, and glassy luster. Common inclusions might be tourmaline, rutile, or various metallic ores.
